Rotary refrigerating apparatus.

closes said vdve by oeting in the mer cury. The mercury during the operation of the machine enters the conduit 5 through the valve 57, and is ied into tne pipe on its We to the oni/'ity el'. it will he noted that t e charges of the refrigerant and plugs of mercury trevei through the spiral port 38 ny reason of the ehr'ects of centrifngel :Sorce Hoving described my invention what l desire to secure by Letters Hit-ent end claim is:

l. in n rotary refrigerating apparatus the combination of a compression chamber, e compressing wheel in seid chamber, e collecting chamber in seid wheel, a spiral port extending from the collecting chember to the `outer periphery of the wheel, means to rotate the wheel, means to circulate cl'inrges of compressing Huid from the compression chamber to the collecting chamber, means to charge the cohecting chamber with the refrigerant after having been volatlized and ineens to leed the compressed refrigerant from the compression chamber.

2. In n. rotary refrigcrating apparet-us the combinetion of compression chamber, a compressing wheel in scid chamber, a. coln looting chamber within the wheel, e spiral port extending from the collecting chamber lecting chamber within the wheel, a spiral conduit extending into the collecting ChinnN ber fof the wheel und with one end fastened to the letter, means to turn the shaft con duit, n lcondensing cooling coii in the comnession chamber, n regulating valve ChemA ler conncccd with the compression chamber, e conduit .leading from the regulating valve chamber and. extending into the collecting clnnnber, n ges inlet pipe connected to the ,seid shaft conduit, and outlet piping extending her.

3. in s rotary refrigernting apparatus the combineon of e compression chamber, e rotative enient therein to compress e volw tile rerigerz it hy means of e compressing iuid, ineens to leed the compressed refrigerroni the reguieting valve cham- ,ent from me compression chamber, ineens to leed the volatile rerrigerant to the rotative 'oer and fastened to the compressing wheel,

and extending into the chamber of said nhcel, un induction pipe in the shaft conduit, n conduit extending from the regulating valve chamber and connecting with the ind notion pip-e7 ineens to rotate the shaft con duit and thereby the compressing wheel, ineens to leed en expanded refrigerant to the shaft conduit, means to lead the rcfrig craint after compression from the valve regulating chamber, and n condensing and cooling coil' in the compression chamber.
